Did you know that you can choose who see's what status posts you make just by adding them to different friends lists?
If you want some people to know something but don't want everyone to know, you can add some friends to different lists in your friends. Like I added some people to the list "Close Friends" and when I post a new status I can pick who see's it.
After adding the people you want to the different lists "Close Friends, Family, Acquaintances" then when you post a status update you click on the little drop down menu and pick who you want to see the status you are posting. Only the people who are in those lists will be able to see it.
This way if you have friends or family that you don't want to have to explain why you posted a picture of the new skull tattoo you just got on your back, you just pick "close friends" as the only people who can see your picture and make sure you haven't added that person or people to that list.
